I'd agree with you on the Queen and Phillip; not sure about any of the rest of them though.
Personally I think when the Queen passes its likely to re-spark a bit of debate about the monarchy
It wouldn't produce the radical change people who want to abolish the royals would expect. The crown estate would revert back to the family ownership and they would then choose to keep them open and retain the profits (currently they go to the treasury). On top of all that they are all, already beyond wealthy and media attractive, they would probably have a greater presence without the royal status protection.
So as above it wouldn't make any real difference with the exception of having to deal with the horrendous prospect of an embarrassing head of state. All things considered I'd rather crack on with a royal family that sure needs some reform but are at least stable and a respected head of state.
